1 PROCESS AUTOMATION. Junction BOX Selection Guide . FOR Fieldbus Infrastructure . ENCLOSURE SOLUTIONS FOR Fieldbus DISTRIBUTION. Delivering Solutions For the last 50 years, Pepperl+Fuchs has been a world leader in hazardous area protection, always striving to provide our customers with the latest technologies in the most cost- effective manner. Committed to providing our customer with a competitive edge, we now offer our expertise in designing and building enclosure solutions. Our FieldConnex segment protector and FieldBarrier wiring interfaces are now available in ready-to- install field Junction boxes.

2 Our Fieldbus Junction box solutions are tailored to meet the demanding needs of harsh operating environments. This value-added solution results in reduced engineering and installation costs. Junction boxes are available in a variety of housing materials and enclosure designs. Our off-the- Typical field Junction box shelf solutions offer a quick turn around for your next project. We not only offer a complete range of solutions for Fieldbus installations, we can also develop custom solutions tailored to specific requirements. If your enclosure needs are on a much larger scale, allow our application engineers to develop your unique solution.

3 This reduces in-house engineering efforts and costs. From concept and design to startup and commissioning, Pepperl+Fuchs will provide custom-engineered field boxes manufactured in our UL508A, UL698A, and CSA approved panel shop. This guarantees the consistent superior quality you have come to expect from Pepperl+Fuchs. Custom engineered solutions are completed in-house by our experts, and we can provide CAD drawings in 2-3 business days. Distributed Architecture In process plants throughout the world, segment protectors and FieldBarriers are used as key components in the distribution of Fieldbus networks from the control room to the field instruments.

4 A trunk and spur topology is commonly used. In a typical Fieldbus installation, 10-12 Fieldbus devices are connected via one cable run that can span between 1500-1900 meters. This one cable supports power and communication to all the devices; therefore, it is recommended to use short circuit protection and energy limitation to isolate a fault condition from negatively affecting device communications on that segment. One device is connected to the output spur of a segment protector or FieldBarrier. Fieldbus Junction boxes are installed close to the instruments in the field in one of two ways depending on the location of the instrumentation: Highly Distributed Architecture Multiple segment protectors Distributed Architecture One segment and FieldBarriers may be packaged together or combined protector/FieldBarrier per enclosure with other components for a custom distribution panel DCS.

Painted Steel Polycarbonate Choose Your Material The enclosure material is an important consideration in planning the Fieldbus network distribution, and it is critical to the overall success of the installation and long- term stability of Fieldbus communications.

ITC cable from the control room to the Junction box, we have a wide range of solutions to make installation quick and easy.

7 It is not uncommon to have different trunk and spur connections, , conduit adapter on the trunk in/out and quick disconnect receptacles on the spurs.

Choose Your Distribution Module Segment protectors and FieldBarriers are key components in the distribution of the Foundation Fieldbus and PROFIBUS PA networks from the control room to the field instruments. FieldConnex distribution modules offer best-in-class segment reliability and simplified installation.

8 Select the distribution interface that matches the application. Segment Protectors: General-Purpose, Div. 2/Zone 2. Segment protectors (current limiting devices) provide additional dependability to the Fieldbus network;. they isolate a single short from affecting the entire network. FieldConnex segment protectors simplify installation and reduce the likelihood of miswiring or over-termination. When the fault is repaired, the segment protector automatically resumes operation of the spur. R2 Segment Protector: The innovative design provides simple installation of field instruments. A key feature is the trunk T-connector.

9 It provides a single location for the terminator, and the segment protector can be replaced without disturbing the trunk. R2 segment protectors support 4-12 spurs. RM Modular Segment Protector: The trunk module connects the unit to the segment and also has two output spurs. Each expansion module has four spurs and simply snap side-by-side on a DIN rail with a system plug for connection. RM segment protectors support 2-26 spurs. FieldBarrier: Zone 1/Class I Div. 1 Spurs (Entity/FISCO Outputs). The FieldBarrier can be installed in Zone 1/Div. 2. In addition to short-circuit protection the FieldBarrier offers galvanic isolation.

10 Each intrinsically safe output can be up to 120 m long. This permits installation of field instruments in Zone 0/Div. 1 and allows live maintenance on the instruments.
